Massive sewer line collapse near D.C.’s Kenilworth Aquatic Gardens has triggered emergency plans that could lead to untreated sewage flowing into Beaverdam Creek. The failure of the 108-inch Anacostia Sewer Force Main threatens to overwhelm wastewater systems serving over 100,000 homes. With heavy rain in the forecast, pressure mounts as WSSC Water prepares for a possible controlled overflow to avoid flooding in Northeast neighborhoods. Officials assure drinking water is safe, but the risk of environmental harm has turned urgent eyes toward the Capitol’s underground crisis.

STORY HIGHLIGHTS

Pipe Collapse: A 108-inch sewer line ruptured on July 20 near Kenilworth Aquatic Gardens.

Overflow Threat: Untreated sewage may soon be released into Beaverdam Creek.

Coverage Area: The system serves over 100,000 homes and businesses in Maryland.

Backup Capacity: On-site storage of 7 million gallons is almost full.

Rain Risk: Incoming storms could trigger emergency discharge

Health Measures: Drinking water is unaffected; contact with creek water to be discouraged for up to 30 days.

Public Alerts: If overflow occurs, residents will be informed with details

In a developing crisis that carries weighty environmental and public health implications, Washington D.C. officials are now on high alert following the catastrophic collapse of a massive sewer line on July 20. The damaged line — known as the 108-inch Anacostia Sewer Force Main — plays a critical role in the region’s wastewater system, and its failure has sparked concerns that untreated sewage may soon need to be deliberately diverted into Beaverdam Creek.

As the situation intensifies officials are eyeing a grim but increasingly likely contingency: a controlled emergency overflow from the Anacostia Wastewater Pumping Station located in Capitol Heights. According to WSSC Water, this drastic measure could be initiated as early as Sunday night — a step they emphasize would be taken only if all other containment efforts are exhausted.

“We Are Working to Avoid the Worst” — WSSC Water Speaks Out

In a statement from WSSC Water, the agency acknowledged the severity of the situation but assured the public that every effort is being made to prevent an overflow.

“We are doing everything within our capacity to contain the flow and protect our communities,” the statement read. “Overflowing into a waterway is always the absolute last option. But preventing raw sewage from backing up into homes must take precedence during emergencies.”

Currently, the pumping station is managing 60 to 65 million gallons of wastewater per day — all from a network of more than 100,000 homes and businesses across Maryland’s Montgomery and Prince George’s counties. That wastewater typically flows through the now-compromised main toward the Blue Plains Advanced Wastewater Treatment Plant, but the collapse has thrown the system off balance.

Rain in the Forecast Adds Pressure to a Fractured System

While the damaged pipeline itself has caused significant challenges, the possibility of rainfall looms as an additional and dangerous variable. Rainfall could sharply increase system inflow, putting pressure on storage capacity that’s already running near its maximum.

WSSC Water has 7 million gallons of on-site emergency storage at its disposal. However, once that volume is surpassed — a scenario that becomes increasingly probable with each passing hour — the utility may have no alternative but to allow wastewater to flow directly into Beaverdam Creek, which ultimately drains into the Anacostia River.

“It’s a Delicate Balancing Act” — Officials Weigh Options Carefully

Environmental and municipal authorities are walking a tightrope as they weigh infrastructure risk against public health concerns.

“It’s a delicate balancing act between what is environmentally ideal and what is logistically necessary,” said one official close to the operation. “No one wants to release untreated sewage into any waterway. But the alternative — flooding people’s homes and streets with raw sewage — could be disastrous on multiple levels.”

To help protect the vulnerable repair site near the Kenilworth Aquatic Gardens in D.C., D.C. Water has already installed temporary retaining walls. These structures are intended to hold back overflow pressure and buy more time while a long-term solution is engineered.

Water Safety Intact — Potomac Still Unaffected

One silver lining in this unfolding emúergency is that the region’s drinking water remains safe. Officials clarified that both Maryland and D.C. residents get their tap water from the Potomac River, not the Anacostia — and certainly not from the potentially affected Beaverdam Creek.

Nonetheless, WSSC has promised that if any overflow does occur, public warning signs will be posted swiftly and clearly along the creek and its surrounding areas. Residents will be advised to avoid any contact with the water for up to 30 days due to contamination risks.

Public to Be Notified — Timing, Volume, and Duration Will Be Shared

In an effort to maintain transparency, WSSC stated that if and when the overflow is triggered, detailed public updates will follow. This includes the exact start time, estimated volume of untreated discharge, and confirmation once the release ends.

“We’re working closely with health and environmental departments across both jurisdictions,” WSSC’s update read. “This is an interagency effort, and public safety remains our guiding concern.”

Until then, residents are left in a state of anxious waiting. With the system under strain and the weather unpredictable, all eyes remain fixed on the skies — and on the flow meters at the pumping station.

As Washington’s underground crisis deepens, the looming decision to release untreated sewage into Beaverdam Creek stands as a harsh testament to failing infrastructure and urgent necessity. With every drop of rain, pressure builds on a fragile system already stretched beyond its limits. While officials strive to protect homes and preserve health safeguards, the risk to waterways and ecosystems casts a long shadow. For now, the capital holds its breath—awaiting either recovery or release—as the city’s lifelines teeter on the edge of overflow.
